CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 459,958, datedSeptember 22, 1891.

Application filed April 6, 1891. Serial No. 387,898. (No model.)

To all whom it may concern.-

Be it known that I, CHESTERFIELD M. COLE, a citizen of the UnitedStates, residing at Sulphur Springs, in the county of Ohio and State ofKentucky, have invented certain new and useful Improvementsin CarCouplers, of which the following is a specification, reference being hadtherein to the accompanying drawings.

My invention relates to an improvementin car-couplers; and it consistsin the peculiar features of construction and arrangement of parts, morefully described hereinafter, and definitely pointed outin the claims.

The object of my invention is to provide a simple, effective, andconveniently-operated automatic coupler for cars. This objectI attain bythe constructionillustrated in the accompanying drawings, wherein likeletters of reference indicate like parts in the several views, and inwhich Figure 1 is a side elevation of a car with my improvement thereon.Fig. 2 is a detail view of the coupler, partly in section; and Fig. 3 isa detail view of the cam and linklifter.

In the drawings, A represents the car, B the draw-head, and C thedraw-bar. The draw-head is divided into two parts, in which thelink-opening is made, and the link is provided with a head.

The lower portion of the'draw-head is provided with a longitudinalgroove D, in which is located a cam E, having a circular upper edge andan inclined rear. Beneath this cam is located a link-lifter F, theforward end of which projects to a point directly back of theretaining-wall of the link-opening, while the rear end extends back to apoint in the rear of the cam. This lifter is seated on a cross-pin f,which prevents its longitudinal movement, while its under edge isbeveled, which permits of a tipping movement being given the same. Thecam is pivoted on a lifting-bar G, extending through the sides of thedraw-head of the'outside of the car, where it is provided with asuitable crank for turning the same.

The upper part of the draw-head is hinged to the lower part, and is heldin contact therewith by a flat spring H.

When the link is forced in at the link-opening, the parts separate,permitting the head thereof to pass in back of the walls of the opening,thereby being locked in place automatically. When it is desired touncouple the cars, the handle is turned, orachain may be applied to anoffset on the handle, thereby throwing the cam, raising the upperportion of the draw-head against the tension of the spring, and bringingthe rear portion of the cam in contact with the inclined portionof thelink-lifter, thereby raising the forward end of the lifter, which inturn raises the link-head beyond the locking-walls of the jaw andpermitting the same to be readily withdrawn.

I am aware that many minor changes in the construction and arrangementof the parts of my device may be made without in the least departingfrom the principle and nature of my invention.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. In a car-coupler, the combination, with the draw-head having adivided head,the upper portion of which is hinged to the lower portion,and having a central longitudinal channel and link-opening therein, of acam-- pin-actuating rod for the cam pivoted in the head, a link-lifterin the channel below the cam, having an inclined under rear end portion,with which the rear end of the cam engages, its front portion extendingforward to a point adjacent to the locking-wall of the head,substantially as described.

2. In a car-coupler, the combination, with thedraw-head having its upperportion hinged, and a spring for normally holding the same in place, ofa cam for raising the upper portion, and a link-lifter pivoted below thecam, its under rear edge being beveled and with which the rear end ofthe cam engages and its forward portion extending back of thelockingwall of the head, whereby the upper portion of the head and thelink are disengaged by single movement of the cam, substantially asdescribed.

In testimony whereof I affix my signature in presence of two witnesses.
